Dear MySQL users,

MySQL Connector/J 8.0.7 Development Release is a development milestone release for the 8.0.x series.
This release includes the following new features and changes, also described in more detail on https://dev.mysql.com/doc/relnotes/connector-j/8.0/en/news-8-0-7.html

MySQL Connectors and other MySQL client tools and applications now synchronize the first digit of their version number with the (highest) MySQL server version they support.
This change makes it easy and intuitive to decide which client version to use for which server version.

Connector/J 8.0.7 is the first release to use the new numbering. It is the successor to Connector/J 6.0.6

As always, we recommend that you check the “CHANGES” file in the download archive to be aware of changes in behavior that might affect your application.

To download MySQL Connector/J 8.0.7 dmr, see the “Development Releases” tab at http://dev.mysql.com/downloads/connector/j/

Enjoy!


Changes in MySQL Connector/J 8.0.7 (2017-07-10, Development Milestone)

MySQL Connectors and other MySQL client tools and
applications now synchronize the first digit of their version
number with the (highest) MySQL server version they support.
This change makes it easy and intuitive to decide which
client version to use for which server version.

Connector/J 8.0.7 is the first release to use the new
numbering. It is the successor to Connector/J 6.0.6.

* Functionality Added or Changed

* Bugs Fixed

Functionality Added or Changed

* X DevAPI: There are changes to some methods related to
the Result interface:

+ getLastDocumentId() and getLastDocumentIds() have
been replaced with getDocumentId() and
getDocumentIds(), which are put under a new
AddResult interface that extends Result.

+ A new getAutoIncrementValue() method is added to the
new InsertResult interface that extends Result.
See MySQL Connector/J X DevAPI Reference
(http://dev.mysql.com/doc/dev/connector-j) for more
details. (Bug #25207784)

* X DevAPI: It is no longer permitted to pass an empty
search condition, such as the NULL value or an empty
string, to the Collection.Modify() and
Collection.Remove() methods.

* X DevAPI: Connections using the X Protocol are now secure
by default. Also, the xdevapi.ssl-enable connection
option has been replaced by the xdevapi.ssl-mode option,
which has DISABLED, REQUIRED (default), VERIFY_CA, and
VERIFY_IDENTITY as its permitted values; see the
description for the new option in Configuration
Properties
http://dev.mysql.com/doc/connector-j/8.0/en/connector-j-
reference-configuration-properties.html
for details.

* X DevAPI: Consolidated the BaseSession, NodeSession, and
XSession interfaces into a single
com.mysql.cj.api.xdevapi.Session interface. The following
related changes were also made:

+ Renamed XSessionFactory to SessionFactory.

+ Consolidated the AbstractSession, NodeSessionImpl,
and XSessionImpl classes into the
com.mysql.cj.xdevapi.SessionImpl class.

+ Removed the Session.bindToDefaultShard() method and
the VirtualNodeSession interface.

+ The mysqlx.getNodeSession() method has been renamed
to mysqlx.getSession() and it now returns a Session
object.

+ The DatabaseObject.getSession() method now returns a
Session object (instead of the old Session
interface).
See MySQL Connector/J X DevAPI Reference
(http://dev.mysql.com/doc/dev/connector-j) for more
details.

* To avoid using JDBC statements inside core Connector/J
classes, the following changes have been implemented:

+ Created a new com.mysql.cj.api.Query interface,
which is implemented by StatementImpl.

+ Replaced the
com.mysql.cj.api.jdbc.interceptors.StatementIntercep
tor interface with the
com.mysql.cj.api.interceptors.QueryInterceptor
interface.

+ Added a new method, PacketPayload
preProcess(PacketPayload queryPacket), to
QueryInterceptor.

+ Renamed the connection property
statementInterceptors to queryInterceptors. See
Configuration Properties
(http://dev.mysql.com/doc/connector-j/8.0/en/connector-j-
reference-configuration-properties.html)
for details.

* Added Japanese collation for the utf8mb4 character set.

Bugs Fixed

* X DevAPI: createView() failed with a NullPointerException
when there were null inputs to it. This fix adds checks
for nulls, and makes Connector/J throw the proper errors
for them. (Bug #25575156)

* X DevAPI: createaTable() failed with a
NullPointerException when there were null inputs to it.
This fix adds checks for nulls, and makes Connector/J
throw the proper errors for them. (Bug #25575103)

* X DevAPI: The connection properties
enabledSSLCipherSuites, clientCertificateKeyStoreUrl,
clientCertificateKeyStoreType, and
clientCertificateKeyStorePassword were ignored for
connections using the X Protocol. (Bug #25494338)

* X DevAPI: Calling getNodeSession() with an URL string
containing SSL parameters caused a
CJCommunicationsException. This has been fixed by
creating a byte buffer to handle SSL handshake data.
(Notice that getNodeSession() has since been consolidated
into getSession().) (Bug #23597281)

* X DevAPI: Concurrent asynchronous operations resulted in
hangs, null pointer exceptions, or other unexpected
exceptions. This has been fixed by correcting a number of
problems with the SerializingBufferWriter and by limiting
the number of buffers sent with a gathering write. (Bug
#23510958)

* X DevAPI: When a thread failed to make a connection to
the server using the X Protocol, the client application
hung. A new connection property,
xdevapi.asyncResponseTimeout (default value is 300s), now
provides a duration beyond which the attempt to connect
timeouts, and a proper error is then thrown. See
description for the new option in Configuration
Properties
(http://dev.mysql.com/doc/connector-j/8.0/en/connector-j-
reference-configuration-properties.html)
for details. (Bug #22972057)

* Connector/J failed a number of regression tests in the
test suite related to geographic information system (GIS)
functions, because of changes to GIS support by the MySQL
server. The fix corrects the tests. (Bug #26239946, Bug
#26140577)

* Configuration templates named by the connection property
useConfigs were not recognized by Connector/J. (Bug
#25757019, Bug #85555)

* A NullPointerException was returned when getDate(),
getTime(), or getTimestamp() was called with a null
Calendar. This fix makes Connector/J throw an
SQLException in the case. (Bug #25650305)

* An ArrayIndexOutOfBoundsException was thrown when a
server-side prepared statement was used and there was a
NULL in a BLOB, TEXT, or JSON type column in the
ResultSet. (Bug #25215008, Bug #84084)
